7. Operating pre-requisites
The storage tanks are to be exclusively installed as per the conditions given on the rating plate. The
maximum permitted pressure should correspond to the rated pressure stated on the rating plate. The
connection conditions of the local electricity and water supply companies as well as the assembly and
operating instructions are to be observed in addition to the legally recognised regulations and standards.
The room in which the equipment is to be operated must be frost-free. The assembly of the equipment
has to be carried out in one place and taking into account the cheapest method; i.e. the equipment
must be easily accessible and capable of being exchanged in the event of any maintenance, repairs and
possible exchanging of components being required. The hot water storage tank may only be connected
to fixed pipework.
In order to allow for a trouble-free repair, a removal or exchange of the device, it is necessary to establish
the connection of the tank by means of a detachable connection (Dutch). Tank leaks as a result of an
improper connection and resulting damage and consequential damage are excluded from the warranty
and product liability.
In the event of the water containing high quantities of lime, we recommend the upstream installation of
a commercially available de-calcification device or having a maximum operating temperature of 60°C
(Setting Pos.
) In order to avoid any infestations, we recommend the upstream installation of a water
filter.
Should a device, at the point of delivery, clearly display a malfunction, damage or other defect, this
must not be fitted, installed or used in the system. Subsequent complaints regarding devices with an
obvious defect which have been connected and installed are expressly excluded under the warranty
and guarantee.
8. Assembly and Safety Instructions
a) Important assembly instruction! Do not bend the suspension hooks to avoid
the danger of fracturing Failure to observe this may result in the risk of injury
due to the equipment falling down!
b) A wall rail for suspending the upper fixing hook is included in the packaging of each
appliance, which should be fastened into the wall using two screws .to support the
weight of the equipment. Two further fastening screws are to be provided to act
as the lower wall brackets of the equipment (in accordance with the dimensional
drawing with the equipment dimensions) to prevent lateral movement. The lower
wall bracket has no supporting function and may therefore not be subject to any
excessive stress. Lifting and/or supporting the electrical storage heater on the lo-
wer wall bracket is prohibited, as this strain can lead to the wall bracket tearing off!
Hot water heaters in the suspended version may not be mounted in a horizontal
position.
c) During the assembly process the dimensional drawings of the equipment and any possibly included
instructions are to be observed. The attachment hook is always to be secured to the rear wall of the
tank with at least two screws.
Caution: Only fixing hooks provided by the manufacturer may be used!
If the assembly height is
changed, this is to be tightened to the mounting screws with a torque of 40 - 50 Nm.
d)
Warning
: The weight of the hot water heater including the weight of the hot water it contains (of the
rated capacity) is to be taken into account for any load-related and strength-related dimensioning of
the equipment‘s mounting surface or for selecting the mounting location..
Special suspension methods:see thin-walled suspension
e) If a hot water boiler is fitted with surrounds (cladding) in confined, small areas or in false ceilings and
similar things, care must be taken to ensure that the connecting side of the equipment (water connec-
tions, electrical connection compartment or heat installation) remains freely accessible and that no heat
build-up takes place. There must be an unencumbered space of 500 mm for removing the heating
flange. A free-space of a minimum of 50 mm above the equipment must be reserved for suspending it
on the wall rail.
